Display opens on greening Empire State Building

The iconic Empire State Building has unveiled an interactive, multi-media sustainability exhibit promoting its $20million green retrofit.

The showcase, which cost $2million, explains the energy retrofit project that was announced in April last year by with former president Bill Clinton and New York City mayor Michael Bloomberg.

Plans for the building aim to reduce its energy use by more than 38%, cut energy bills by $4.4million a year and reduce carbon emissions by 105,000 metric tons over the next 15 years.

To bring the energy retrofit program to life, Seattle-based design firm Hornall Anderson were chosen to create a 'tangible and engaging' sustainability exhibit.

A spokesman said: "The installation aims to educate the millions of people who visit the building every year on the positive global impact of both energy efficient building and sustainable living practices."
